Application and new, 1914, Scria1 No. 830,010. Renewed Ma 1,1917.- Serial no. 165,793.,

To all whom it may concern:

Be it known that I, Josnrn I a citizen of the United States, and a resident of Branford, county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Automatic Train- Pipe Connectors, of which the following is a specification.

- s invention relates to automatic train pipe connectors for railway cars and has among its objects to provide an improved support for the connector head which will be simple and stron and permit free univer'sal movement of t e head in service.

To this end theinvention consists in the combinations, arrangements and construe-- tions which will be hereinafter, fully detrated in the accompanying drawlngs, in which:

Figure 1 is a side elevation of my imguiding prongs 26 for alining the heads on proved connector, and

Fig. 2, is a longitudinal sectional plan view thereof.

Referring to the drawings: My invention comprises a two-piece base A bolted togather. and to a lug '10- of the car by bolts 11; e base is provi ed with undercut seatsor grooves 12 and 13 within which a supportis assembled and bolted together.

uncoupled position. v

The is interpogid between the connector head a stem 14 leading f om a fluid conduit 15.

shoulder and upon said ribs the forward end;

of the spring B is seated, the distance fiom said shoulder to the head 16 of the stem being'such as to maintain the spring normally under slight compression.

V. RoBrNsoN,

and the base A and surrounds The stem and conduit 15 are connected in 4 any suitable manner, the latter being curved so as to diverge laterally of the stem and head C at a point back of the head and in the connector head C and through the latter;

A gasket 25 of any desired construction and material is mounted in the forward end of Y the portion 23 to insure proper air tight connection when two connector heads couple up in service. K

I have shown awonnector head 0 of the butt-face type having two diagonally spaced forwardly extending outwardly ,dlverging curves, etc. "However, in lieu of this form of 1 head, any suitable type may be used with my improved support.

en two automatic ponnectors constructed according to my invention come together in theact of coupling, the heads O are accurately alined by the guiding prongs '26, the sprin B alinementu l u the cars will compress the supporting spring B and eifect a tight and efiicient joint beielding to permit, of such rt or forward movement of tween the face of the connector heads C. In uncoupling, the operation of the con nectors Wlll be the reverse of this. Having' thus described my-said inyention, what I c im as new and desire to secure by United States Letters Patent is:

1. An automatic train pipe connector comprising, in combination, a' base provided with a groove in one face, a connector head,

' a fluid conduit extending through the head and diverging to one side of the head in rear thereof, a stem connected with the conduit and extending rearwardly to the base, and a spiral supporting spring seated in the.

groove in the base and acting against said conduit to extendthe head.

2. An automatic train pipe connector comprising, in combination, a base provided with a groove in one face, a connector head, a fluid conduit extending through the head and diverging to one side of the head in rear thereof, a stem connected with the conduit and extending rearwardly through the base,
